Application and November 14, 190s. serial No. 462,559.

T0021 tchom 'it y/mz'z/ {fonc-cwi lie it known that I. lVrLLAnn P.Pausoxs;

.aitizen of the United States, residing in `the city of I `lnshing`county of Queens. and j y State of New York, have invented a certain newand useful Improifcinent iu Methods of l A'Ianufacturing Coal-Gras andCoke, of which i the following is a. specification.

` bers.

My invention relates to the vmanut'acture of coal gas and coke, and theobject of my invention is to produce a maximum yield of gas andy atithesame time produce coke of the best quality. l

In ordinary coal `gas practice the maxi mum yield of gas may beobtained. but the coke is of an inferior quality, being soft and spongy,While in ordinary'.by-product coke oven practice the coke is ofV a goodquality but only a partof the total'yield of gas is obtained as abit-product.. B v the use of my invention I am able to obtain a yield ofgas equal to-.that of the best coal practice and a. yield of coke equalto that of the best coke oven practice. -I accomplish these results bythe use of the method of nianufacture herein described in connection'vvit-h the apparatus Which is shown in the;.`preferred form 4in theaccompanying' drawings.-

Referring' the drawings, which Aillustrate a plant having' two chambersheated from ,a common grate, Figure 1 is a vertical section ,through oneof the' distilling cham- Fig. 2 is a partial vert-ical section throughlone of the walls adjacent. to each distilling chamber. v sectionthrough the line a-b of Figs. 1 and showing the line n rl on which the.-section of Fig. 2 is taken. Fig. 4 is a rear View of the lower part ofthe plant showing the furnace. Fig. 5 is a front elevation showing onechamber open and the other with its door closed.

A is a distilling chamber having' its top andbottom inclined. It'ischarged with coal through the yopening B at the top, which is thensealed. At the bottom of the inclined chamber is a swinging door Cthrough Fig. 3 is a horizontalA l all-parts of the chamber.. Todistribute the heat from the furnace I make the side walls of eachchamber hollow, and arrange therein a matin line F which has the sameinclinaition as that of the'chamber, and lead from said main flue avseries of'vertical lues G'. as l will be seen in Fig. 2 and in dottedlines in Fig. 1. The Vertical fines G open into a top line H, whichcommunicates with the discharge tlue I leading' to the stack or anydesired point where the excess heat mav be used. Furthermore, as acontinuation of the incline ofthe main flue F, I arrange a dependingapron at the rear of the furnace beneath which the entire heat must passfrom the furnace to the inain tine.

The .o eration of my invention is as foil. lows: T e distilling chamberis charged the coal, fand l obtain a better grade of coke than' isusuallyT obtained from the manufac ture of coal gas, because of thefact. that at the time the gas is leaving the coal and the coal is beingconverted into coke. The con` pressure due to weight is distributed moreevenlyI throughout the massthan under presovens -Thisl distributionisdue to the fact that. there is a substantial pressure accumulated inthe mass in more than 'one direction. l.

It will be obvious to thoseskilled in the not Wish to be understoodasilimitging inyselt' to any particular form of apparatus.

Havilng1r described my vinventioinavhat l claim is: 5

The methodl of manufacturing lcoal gas and coke which consists incompletely -flhng with coal so that it is almostentirely filled. and thechargingy opening' is then scaled.

art thatmyA method of manufacture may be carried on in other forms ofapparatus from that Which'l have shown herein, and I doV manufacture lobtain all ot' the lfas from dition of the mass is such that theinternal ent practice, either in gas retortsjor 'coke a relatively longund high. `air tight cha-1nber with a'. mass of coal, supporting themass at an angle slightly greater than the angle ofrest of the 'massduring distillation so 5 that there will be a substantial und nearlyuniform pressure due to gravity through- /out all parts of the mass,subjecting the mass to auniformly distributed external hea-t, i
